You are right, I didn't catch the glue was supposed to be in .com wehere
the NSes are, which are someone else's - doh - I expect that someone who
providers nameservers takes care of gluing them appropriately, so it can

You are absolutely right, a small misreading in the scenario, my .org
servers are of course glued in .org, if I had used all the NSes of the
registrar (in .net, .com whatsoever), those of course would be glued in
their corresponding parent zones. I expected that to be obvious and clear,
as I said, I misread the scenario in the end and assumed that provided
NSes are properly glued by their operators.

Agreed at some point we need glue and wherever a full delegation of a
subzone is done, we need to have glue, no doubt ;-).
